Dunno. He’s been smoking for a looooong time and it ain’t got him yet. Once heard a guy tell him, “Jack we care about you and think you should quit smoking so we can have you around for a good while.” Jack thought about it and responded, “Well, my grandad lived to be a very old man.” The guy looks surprised and says, “He smoked too?” To which Jack says, “No. He minded his own damn business.”
